Not nearly as funny as it is to see people baselessly attacking Apple be presented with facts that refute their cynical and unsupported takes, then resort to the classic "...you're just a fanboy!"

Devils advocate No more than your proof it's not.

Can they release a software update to fix the back glass cracking too?
I don’t think the titanium has anything to do with overheating. I think it’s either the A17 Pro chip, iOS or, at worst, poor design when it comes to overall cooling.
People are quick to blame third party apps, but if approved apps with no malicious intent can cause such issues, then it is Apple and their OS at fault, in my opinion. Their OS should not allow third party apps to push hardware to potentially dangerous operating levels.

The onus is on the person making the claim. I never stated my belief nor did I make any claim. I asked for proof from the person making the claim. Your attempt to play gotcha with me failed.
instagram app update just showed up on App Store. Wonder if that includes their fox?
Well, yes, it’s a combination of all together, and the fix will be a cleverly hidden scheduler tweak to limit the cpu/gpu resources availability or/and runtime throttle. The titanium grade 5 frame contributes to the overall poor hardware design problem, Apple will deny this till they get pushed against the wall.
I just hope few testers out there don’t upgrade, simply to prove the throttle and set up a class action.

It wouldn't be MacRumors if that didn't happen!
This is not a butterfly keyboard situation. And managing voltages, clocks, cycles, that’s quite standard, though you have no idea if that is what they are doing.
And how do you know titanium caused any issue, and what “hardware design problem”? What evidence do you have?
Thermal conductivity or the ability of a given material to conduct/transfer heat is 237 W/m·K (Watts per meter Kelvin) and titanium is 24. Titanium conducts heat about 10 less easily that Aluminum. Changes to software will not alter the rules of physics. But softwares throttling the Phone will help generate less heat. See September 26th rumor from Kuo--https://www.macrumors.com/2023/09/26/iphone-15-pro-overheating/
Those are details we’ll get once a class action shows up.
But funny that you mentioned the butterfly keyboard, i even forgot about it despite being affected, yeah just another hardware fiasco that Apple denied till they got pushed against the wall by a class action. Btw. the MacBook was so poorly designed, they even couldn’t replace the keyboard without replacing the battery.

Yes, just in case anybody wants to compare, here is long list of the thermal conductivity of many metals, metallics, and alloys.
Thermal Conductivity of Metals and Alloys: Data Table & Reference Guide
Thermal conductivities of common metals, metallic elements and alloys.
www.engineeringtoolbox.com
Which Titanium alloy are you referring to? It matters.
Grade 5 Titanium (actually Ti-V-Al) 6.7 W/m-K
Pure Titanium. 11.4 W/m-K
Stainless steel (304) 16.2 W/m-K
Carbon steel 45 W/m-K
Aluminum. 235 W/m-K
Copper 398 W/m-K
No, material wise it’s worse…
Titanium thermal conductivity λ=15.24W/(m. K), about 1/4 nickel, iron 1/5, aluminum 1/14, and a variety of titanium alloy thermal conductivity than the thermal conductivity of titanium decreased by about 50%.
The thermal conductivity of stainless-steel ranges between 20-60 W/(m.K). Generally speaking, stainless steel has higher thermal conductivity than titanium and is thus more suitable for applications that require heat transfer or rapid cooling.
Titanium Vs Stainless Steel: Which Metal is Right for Your Project?
Titanium may be the right choice for your project if you’re looking for a lightweight yet strong material with superior corrosion resistance.www.madearia.com
Run benchmark stress tests between the 15 Pro and the 14 Pro. The 15 Pro radiates FAR more heat from the aluminium/titanium side rails than any of the stainless steel side rail phones does.
If you actually look into things instead of pretending to know what you're talking about you'll be less likely to be wrong.
I haven't had much of an issue with this. Some heating in the first day and that night, but then it cleared up.
THEN I fired up Instagram and boy howdy. 🔥
Turned off the background refresh on IG. Everything has been great since then.
FWIW, IG did this on my last phone (12 Pro) too. And turning off background refresh solved the issue there, too.

It's really quite bizarre because anyone with a 15 Pro and a 12/13/14 Pro can just easily test this themselves. The difference in heat radiation on the side rails is night and day.
How should Apple QC the apps which are causing the issue?

Verizon screwed up my order and I haven't got around to reordering the 15 Pro Max with the lead times as they are. Perhaps this is fate telling me to skip this year.
Actually, heating up a processor is trivial to do via software. All you have to do is to execute code that ramps the CPU up to 100% over a lengthy period of time. Keep in mind most CPU’s and GPU’s have heat tolerances up to 110-120C. That’s above the boiling point of water. The hardware can handle it, though it might suffer damage over a lengthy period of time, but it’ll burn any human who touches it. Try touching the bottom of an aluminum laptop after it’s been running at 110C for a while. It’ll be very, very hot. And that’s considered normal. Companies use software to regulate the balance and tradeoffs between heat and performance. That makes overheating mostly a software problem. The hardware just does what it’s told to do by the software. If the software doesn’t regulate that balance properly, then it gets really hot.
As someone who does crypto mining, it’s very easy to overclock memory on a GPU to get it up to 110C sustained and run it for months. I wouldn’t recommend touching anything near it. I can tell you that NVidia GPU’s will start throttling hard if you drive it to 115C. A phone is a tiny piece of hardware compared to a large GPU in a computer case, which will often have a lot of empty air around it and massive fans to blow out excessive heat, something a phone doesn’t have. For the large GPU, your room turns into a sauna, but for a phone, that’s a problem because there’s so little space for dissipating heat. Not even a vapor chamber would be enough to stop the phone from being too hot to touch. Keep in mind the rails of the phone are millimeters from the motherboard.
The titanium frame does not contribute to heating but it does show the user he/she has fingerprints 
I know it's par for the course on MacRumors, but it's pretty entertaining we're now discussing thermal conductivity.
